The England defender has been plagued with knee injuries throughout his career, and played only a handful of games last term.
Redknapp has said that despite the centre half’s quality, the club cannot afford to renew his contract if he is constantly unavailable.
“Ledley’s a difficult one. He has to play this year. I can’t go to the chairman and say: “Give Ledley a contract,” if he has only played two games because he isn’t going to do that,” he told the clubs official website.
“This is Ledley’s big year, he’s got to play 20 games or so, really. Ledley needs to put some games in this year to get another contract,” he continued.
Redknapp also confirmed that both Scott Parker and Emmanuel Adebayor will make their Spurs debut’s against Wolves at Molineux on Saturday, and that he had an interest in bringing David Beckham to White Hart Lane should he be available.
Finally, when asked about want-away playmaker Luka Modric, Redknapp stated that letting the Croatian go may be an option.
“I’ve always been brought up with the belief that if someone didn’t want to play for your club then you move them on and bring someone in who does. And I was of that opinion in the end. If Luka doesn’t want to be here then take the £40million and move on,” he concluded.
Spurs are pointless from their first two game of the 2011-12 Premier League season, and the fans will demand they get off the mark against Wolves today.
